fails to respond to one of these checks, the IMM generates an OS timeout alert and restarts the server. After the server is restarted, the OS watchdog is disabled until the operating system is shut down and the server is power cycled. To set the OS watchdog value, select a time interval from the menu. To turn off this watchdog, select 0.0 from the menu. To capture operating-system-failure screens, you must enable the watchdog in the OS watchdog field. Loader watchdog Use the Loader watchdog field to specify the number of minutes that the IMM waits between the completion of POST and the starting of the operating system. If this interval is exceeded, the IMM generates a loader timeout alert and automatically restarts the server. After the server is restarted, the loader timeout is automatically disabled until the operating system is shut down and the server is power cycled (or until the operating system starts and the software is successfully loaded). To set the loader timeout value, select the time limit that the IMM waits for the operating-system startup to be completed. To turn off this watchdog, select 0.0 from the menu. 4. Scroll to the bottom of the page and click Save. Setting the IMM date and time The IMM uses its own real-time clock to time stamp all events that are logged in the event log. Note: The IMM date and time setting affects only the IMM clock, not the server clock. The IMM real-time clock and the server clock are separate, independent clocks and can be set to different times. To synchronize the IMM clock with the server clock, go to the Network Time Protocol area of the page and set the NTP server host name or IP address to the same server host name or IP address that is used to set the server clock. See "Synchronizing clocks in a network" on page 18 for more information. Alerts that are sent by e-mail and SNMP use the real-time clock setting to time stamp the alerts. The clock settings support Greenwich mean time (GMT) offsets and daylight saving time (DST) for added ease-of-use for administrators who are managing systems remotely over different time zones. You can remotely access the event log even if the server is turned off or disabled. To verify the date and time settings of the IMM, complete the following steps: 1. Log in to the IMM where you want to set the IMM date and time values. For more information, see Chapter 2, "Opening and using the IMM Web interface," on page 9. 2. In the navigation pane, click System Settings and scroll down to the IMM Date and Time area, which shows the date and time when the Web page was generated. 3. To override the date and time settings and to enable daylight saving time (DST) and Greenwich mean time (GMT) offsets, click Set IMM Date and Time. 4. In the Date field, type the numbers of the current month, day, and year. 5. In the Time field, type the numbers that correspond to the current hour, minutes, and seconds in the applicable entry fields. The hour (hh) must be a Chapter 3. Configuring the IMM 17

fails to respond to one of these checks, the IMM generates an OS
timeout alert and restarts the server. After the server is restarted, the
OS watchdog is disabled until the operating system is shut down and
the server is power cycled.
To set the OS watchdog value, select a time interval from the menu. To
turn off this watchdog, select
0.0
from the menu. To capture
operating-system-failure screens, you must enable the watchdog in the
OS watchdog
field.
Loader watchdog
Use the
Loader watchdog
field to specify the number of minutes that
the IMM waits between the completion of POST and the starting of the
operating system. If this interval is exceeded, the IMM generates a
loader timeout alert and automatically restarts the server. After the
server is restarted, the loader timeout is automatically disabled until
the operating system is shut down and the server is power cycled (or
until the operating system starts and the software is successfully
loaded).
To set the loader timeout value, select the time limit that the IMM waits
for the operating-system startup to be completed. To turn off this
watchdog, select
0.0
from the menu.

Setting the IMM date and time
The IMM uses its own real-time clock to time stamp all events that are logged in
the event log.
Note:
The IMM date and time setting affects only the IMM clock, not the server
clock. The IMM real-time clock and the server clock are separate,
independent clocks and can be set to different times. To synchronize the
IMM clock with the server clock, go to the
Network Time Protocol
area of
the page and set the NTP server host name or IP address to the same server
host name or IP address that is used to set the server clock. See
“Synchronizing clocks in a network” on page 18 for more information.
Alerts that are sent by e-mail and SNMP use the real-time clock setting to time
stamp the alerts. The clock settings support Greenwich mean time (GMT) offsets
and daylight saving time (DST) for added ease-of-use for administrators who are
managing systems remotely over different time zones. You can remotely access the
event log even if the server is turned off or disabled.
